YARN Tension roe WINDING-MACHINES.

Specification of Letters Patent.

Patented J une 24, 1919.

Application filed October 5, 1913. Serial no. 256,947.

To all whom it may concern:

Be it known that I, ALoNzo E. RHoADEs, a citizen of the United States,and resident of Hopedale, county of Worcester, State of Massachusetts,have invented an Improve ment in Yarn Tensions for Winding-Machines, ofwhich the following description, in connection with the accompanyingdrawing, is a specification, like characters on the drawing representinglike parts.

This invention relates to improvements in yarn winding machines and theobject thereof is to provide means for maintaining a more even tensionupon the yarn as it is wound upon the yarn receiving means and also ofmore effectively guiding the running strand as it approaches said yarnreceiving means.

More specifically the invention relates to improvements in spoolers orwinding machines of like character in which a spool or other yarnreceiving means rotated by suitable mechanism draws the yarn from a yarnsupplying means such as a bobbin or cop the speed with which the yarn isdrawn by the yarn receiving means from the yarn supplying means. Thiscauses a variation in the tension upon the running strand. Where theyarn supplying means is in the form of a bobbin or cop having a fillingwind this variation in the tension on the running strand is accentuatedby reason. of the conoidal. form of the windings.

The principal object of the present inven tion is to provide means formsuring a uniform tension uponthe running strand as it i is wound uponthe spool and this is accom plished in the invention by locating thetension device closely adjacent to the spool or other yarn receivingmeans. The tension de vice thus located preferably is carriedby thetraversing mechanism and is positioned between. said traversingmechanism. and the weight iimveva body ofthe spool or other yarnreceiving de vice. By placing the tension device between the traversingmechanism and the yarn receiving means a uniform tension is alwaysmaintained upon the strand asit leads to the spoolor other yarnreceiving means not withstanding variations in the tension ofthe yarn asit comes from the yarn supplying means.

i Afurther object of the invention is to provide a tension device whichacts to remove or crush any. motes, bunches or kinks which i may passthrough the guide and clearer of the traversing means. a

A furtherobject of the invention is to provide a yarn winding machinewhich shall impose a uniform tension upon each of the running strandsleading to the respective yarn receiving means, and this preferably isaccomplished by partly supporting a weight upon each of the runningstrands between thetraversing mechanism andthe yarn receiving means. i

By providing weights of difi'erent size the mechanism may be adapted foruse with different kinds of yarns and for different tensions," but withuse of the same weights throughoutthe machine a uniform tension uponal1ofthe running strands, will be maintained. l

. A further object of the invention is to provide a tension device ofthe character above specified which may be applied to usual commercialforms of yarn winding machines without material modification of "themachlnes.

Other objects and features of the invention will more fully appear fromthe following description and the accompanying drawings andwill bepointed out in the annexed claims;

o In the drawings;

t Figure 1 is a transverse section ofa sufficient portion of the spoolerto illustrate the application of the present invention thereto, Fig.2 1sa plan new of the guide and clearer and. a preferred form of tensionwhich is adapted to be located between said guide andclearer and theyarn receiving means,

Fig. 3 is a side view of the same Fig. 4 is avvertical sectional View ofthe tension means on lines i 4, Fig. 3,. the being strewn in elevation,and,

iiltl 1 in the usual manner from belts passing around the centralrotating drum 5. The yarn supplying means which is illustrated herein inthe form of a filling wound bobbin or cop 6, is supported upon a spindle7 vcarried by an arm 8 at the bottom of a bracket 9 which is clamped toa rod 10 extending longitudinally of the frame of the machine. Thebracket 9 is provided with an arm 11 which extends in substantialparallelism with the spindle 7 and is provided at its ends with alaterally extending fork 12 which serves as a guide for directing theyarn from the end of the supplying means.

The traverse of the yarn upon the spools is effected through yarnguiding devices carried by a traverse rod 13 which is reciprocatedby thearms 14 through the yoke 15 in theusual 1113111181. The guiding meansfor directing the running strand to cause the same to traverse the spoolmay be of any suitable type which will permit the placing of a tensiondevice between such guiding means and the spool or other yarn receivingmeans so that the tension device may be located closely adjacent to thebody of the spool. A desirable form of combined guiding means andtension mechanism is illustrated herein and comprises a bracket having abody portion 17 which has a partially cylindrical recess 18 to engagethe traverse rod 13 and a clamping member 19 provided with acomplementary cylindrical recess 20, said clamping member being securedto the body member 17 by a set screw 21, so that the bracket may beclamped at any desired position on the traverse rod 13.

The body portion 17 of the bracket has an upwardly extending arm 22which forms a stationary member of the clearer guide for the traversingmechanism. The body portion is also provided with a downward extensionin which a stud 23 is secured by a set screw 24. The stud 23 providesa'support for an L-shaped counterweighted arm 25, the upwardly extendingmember of which has a recess to receive a rib upon the guiding member26, the guiding member 26 being secured to the arm 25 by a set screw 27passing through a slot in said arm into the lower portion of the guidingmember 26. The guiding members 22 and 26 desirably have convergingcurved edge portions 28 and 29 which merge into inclined parallel wallswhich form a slot 30 through which the yarn'passes to the yarn receivingmeans.

By adjusting the movable member 26 the walls of the slot may bepositioned in accordance with the size of yarn being spooled and servenot only to guide the yarn but also to strip from it motes,- burs, etc.,in the usual manner.

It will be understood that other forms of traverse guides and clearersmay be employed and that the above construction is a preferred mechanismto which I have applied my invention.

In the preferred embodiment of the invention illustrated herein the bodyportion of the bracket has a lateral extension 31 which has a smoothweight supporting surface 32 preferably somewhat inclined to thehorizontal when the bracket is fastened to the traverse rod 13. A stud33 extends normal to the central portion of the weight supportingsurface 32. A longitudinally apertured weight 34: rests at its bottomupon said surface 32 and is mounted loosely on the stud 33, the aperturein the weight being of larger diameter than the stud.

The extension 31 desirably projects a short distance beyond the weightsupporting surface and has secured to it a pin or guide 35 provided witha curved end 36. The weight 3-1 is desirably in the form of a frustum ofa cone having a beveled or curved bottom edge 37 to avoid cutting orabrading the strand runnin beneath the weight.

WVeights of different sizes may be employed to provide means forsupplying clifferent degrees of tension, such as may be required bydifferent kinds of yarn or different windings upon the yarn receiver.shows a weight 34 of a larger size and Fig. 5

hence capable of producing a greater tension.

The weights 34 may be protected especlally against accidental orcareless re moval and loss by an inclosing casing 38 conformingsubstantially in contour to the weights 31, having an open bottom and atop 39 providing a. head which may be screwed down upon the stud 33 andsecured at any desired point thereon by a set nut a0.

In the operation of the machine the running strand of yarn 12 is carriedfrom the yarn supplying means 6 through the forked end 12 of the bracket9, thence through the slot 30 between the pivoted and stationary clearermembers or guides 22, 26, thence downwardly around the stud 33 beneaththe bottom of the weight 3-1, thence over the guide 35 to the spool orother yarn receiving means.

The weight therefore is partially carried upon the strands of yarnbetween the guiding or clearing members of the traverse mechanism andthe spool or other yarn receiving means so that the tension is appliedwithstanding the difference in the speed at which the yarn is drawn fromthe yarn supplying means as the traverse bar is raised and lowered.

The weight 34 by being loosely mounted upon the stud 33 rotates as therunning strand of yarn is drawn beneath its base so that any motes,bunches or kinks which may have passed through the slot 30 between theguiding or clearing means 22 and 26 on the traverslng mechanlsm will beironed out before they reach the spool.

It is to be understood that the embodiment of the invention disclosedherein is illustrative and not restrictive and that variousmodifications may be made Within the meaning and scope of the followingclaims.
